Dietary Variation among Nestling Starlings

Abstract

I sampled diets of nestling European Starlings (Sturnus vulgaris L.) in central New Mexico for four consecutive years. The prevalence of prey in these diets varied within and between years, within days, and relative to nestling age and brood size. Dietary diversity was not significantly different between early and late broods. Young birds were fed more diverse diets than older nestlings, and among these young birds, large broods had more diverse diets than small broods. Different broods received different prey, despite similar conditions of location, time, weather, brood size and nestling age.
